MGL Avionics Challenger lite - FREE RDAC-XG

A few Discovery lite customers in 2015 complained about interference on their radios that badly affected certain frequencies. This issue has been resolved from firmware A 1.0.2.6. or higher . The latest version is available as a free download from the manufacturer's website HEREand it is very simple to install.All units, including used or ex-demo stock, are sold with the latest MGL firmware and a full satisfaction or your money back guarantee - see our terms and conditions.

Up to two "Lite” panels can be used in a single system and they can share RS232 ports and CAN bus devices.

A typical comprehensive functionality "Lite” panel may consist of:

A) One or two EFIS panelsB) One RDAC for engine monitoring plus probes as neededC) One SP-6 compass

Add to this:

D) One, two or three autopilot servosE) SP-10 Flap and Trim controller

Also consider the large available range of peripherals from MGL and third parties ranging from VHF radios, navigation radios, transponders, electronic circuit breakers and more.

iEFIS "Lite" range

The stand-alone iEFIS, with built-in AHRS.

The Discovery has a bright non-reflective 7" touch screen of around 1000+ nits. The Explorer has a similar 8.5" touch screen. The Challenger's touch screen is 10.4".They all look, feel and think like an iEFIS. They have the iEFIS G3 CPU and they run the exact same firmware as the full iEFIS system (in other words they use the same binary and sources).

The Discovery looses a rotary control and the 12 buttons under the display which are now a fixture of the touch screen on the left side. The Explorer lite and Challenger lite retain the buttons and knobs.All gain a built in GPS, AHRS with gyros and accelerometers, airspeed pressure sensor as well as altimeter. They connect to peripherals via a CAN bus as well as two RS232 ports.

So, considering the above, we can say the "lite" can do anything a full iEFIS can, subject to having fewer hardware interfaces - but because of that there is no need for a separate iBOX.

The CAN bus supports anything we have - Autopilot servos, engine monitoring modules, flap and trim controller, tranponders, compass, etc. You can also connect an external AHRS if you like and you get RS232 ports for radios, ADSB etc.

There is a small expansion module - if needed, it provides analog and digital inputs, more RS232 ports, a AOA sensor and few additional items. Call it a "mini" iBox if you will.

The "Lite" is a stand-alone system, unlike our normal iEFIS systems where you can have multiple, joined panels in a complex infrastructure.

"Lites" are straight forward to install and make great panels for owners of smaller aircraft who want a sophisticated EFIS but without the cost and complications of a large system.

The Discovery could be viewed as a direct replacement for our popular Enigma. It is similar in panel size but with a bigger, much higher resolution screen and of course is a powerhouse of functionality where needed.
